SCTP reference implementation

Hello,

Can anyone tell me if there are any relatively recent updates to the
SCTP reference inplementation, and if so, from whence it may be
downloaded?

Google took me to http://www1.ietf.org/mail-archive/w.../msg00245.html,
where Randall Stewart was announcing an update to v4.0.3 back in
2001. Randall's link only takes one to his personal page these days,
as well.

The project I'm involved in needs to tunnel SCTP over UDP, and we are
having trouble with the version v4.0.4 of the reference implementation
we have - mainly links ping-ponging up and down every $SMALLNUM
seconds...

Any assistance gratefully received.

Randall Stewart is a member of the development team of FreeBSD too, and
he has been maintaining the SCTP implementation in FreeBSD for a fair
amount of time already.

What this means is: you can get an implementation of SCTP with the
sources of the FreeBSD kernel for free. The 7.0 release of FreeBSD,
which is in the making these days includes a kernel with SCTP support.

You can grab the installable ISO images of 7.0-RC1 from:

http://www.freebsd.org/where.html

or you can simply browse the source code of the kernel at:

http://cvsweb.freebsd.org/src/sys/

HTH,
Giorgos

In a similar vein, STCP source is "in" the Linux kernel.org source
tree. Not sure if it is built by default in the distros though...

And "in" the Solaris/OpenSolaris sources as found on opensolaris.org

Neat! I just finished recloning onnv-gate a while ago, after my old
Solaris system's disk died at home. More fun reading then :)

The problem I have is that half the hardware estate are using a
proprietary daemon/agent which provides SCTP tunneling over UDP on
Solaris. My job is to come up with similar for the Linux boxes, and I
know that using the Linux kernel SCTP stack is not going to talk to
the tunneling stack on the other machines.

I always wanted to be an applications programmer really - this stuff
makes my brain hurt :-)

And netperf should be able to benchmark them all :)
